ToolboxComponentsCreatedEventHandler Delegate

Represents the method that handles the ComponentsCreated event.

Namespace:  System.Drawing.Design
Assembly:  System.Drawing (in System.Drawing.dll)

'Declaration
Public Delegate Sub ToolboxComponentsCreatedEventHandler ( _
	sender As Object, _
	e As ToolboxComponentsCreatedEventArgs _
)

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.Drawing.Design.ToolboxComponentsCreatedEventArgs

A ToolboxComponentsCreatedEventArgs that provides data for the event.

When you create a ToolboxComponentsCreatedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Handling and Raising Events.

The following example code provides a method that attaches an event handler for the ComponentsCreated event of a ToolboxItem. It also provides a ToolboxComponentsCreatedEventHandler event handler method that writes the name of the type of the components that were created to the Console when the event handler is raised by a ComponentsCreated event.

Public Sub LinkToolboxComponentsCreatedEvent(ByVal item As ToolboxItem)
    AddHandler item.ComponentsCreated, AddressOf Me.OnComponentsCreated
End Sub 

Private Sub OnComponentsCreated(ByVal sender As Object, ByVal e As ToolboxComponentsCreatedEventArgs)
    ' Lists created components on the Console. 
    Dim i As Integer 
    For i = 0 To e.Components.Length - 1
        Console.WriteLine(("Component #" + i.ToString() + ": " + e.Components(i).Site.Name.ToString()))
    Next i
End Sub
